I have a model sb6141. I was late paying xfinity and lost internet. My bill is now current and they are saying my internet is fast and everything looks good on their side. But the icon at the bottom is blinking red. I've power cycled several times. I'm at a loss.
The SB6141 is a modem only device. It has no router function or wifi. what router is it connected to?
Netgear WNDR3400v3
The router is connected via coaxial cable to my computer (which is getting internet) and to the Arris via ethernet. When the ethernet cable is unplugged, there is no light at the bottom. But when it's plugged in, it flashes red.
